the system
the decision is the unit of work.
a request may arrive as an email, scan, portal notice or system event. the system carries it from arrival to a prepared answer. a person enters at the point of responsibility.
one complete loop
work enters. a decision comes out.
receive
keep the original, identify the case and start the real clock.
understand
extract the facts and link each one back to its source.
calculate
run versioned rules with exact arithmetic. never ask a model for a number.
prepare
assemble the response, evidence, uncertainties and deadline in one package.
decide
approve, edit or reject the exact result. then send, record and watch it.
a useful comparison
shazam is the height of consumer software. it is the floor for professional work.
shazam turns an uncertain question into a confident answer with one action. no setup. no workflow to learn. no dashboard to maintain.
professional software must begin there, then go further. it must preserve the source, apply exact rules, expose uncertainty, respect authority, carry the deadline and leave an accountable record.
recognition is the beginning. responsibility is the product.
the boundary
three kinds of work. three different owners.
language
read messy material, identify intent, extract facts and draft within a bounded scope.
certainty
calculate figures, enforce rules, control versions and decide what may happen next.
responsibility
handle exceptions, apply judgment and approve the action that leaves the organisation.
proof, not plausibility
every figure carries its source.
the same inputs and the same rule version produce the same result. assumptions are explicit. the source remains attached. calculations use exact decimal arithmetic, never a model.
covered by the verification set.
field comparisons between independent implementations.
differences in value or decimal scale.
the economics
the next workflow should be cheaper than the last.
the first workflow establishes the secure runtime, channels, rule logic, approval records, fallbacks and monitoring.
the next workflow reuses that foundation. only the work changes.
the tenth workflow should cost less to integrate than the ninth.
the end state
your infrastructure. your rules. your records.
the system has a named internal owner, working runbooks, tested fallbacks and no daily dependence on me.
